Give the chemical composition and functions of plasma membrane and cell wall. Differentiate between the two.

(N/A) The plasma membrane is primarily composed of lipids and proteins,while the cell wall is mainly made up of cellulose.
Functions:
- Plasma membrane: It regulates the movement of substances into and out of the cell (selectively permeable) and provides protection.
- Cell wall: It provides structural support,shape,and protection to the plant cell.
